On "Ain't No Grave," a track from his new solo album, the singer-guitarist Luther Dickinson stares death right in the face, quite literally. The song's opening words are "I looked death dead in the eye as he passed me by." But the frontman for the North Mississippi Allstars isn't indulging in morbidity; he's delivering a deeply felt tribute to his late father, James Luther "Jim" Dickinson.
